DETAILED DESCRIPTION

The present disclosure describes technological improvements thatsimplify the identification and presentation of digital supplementsbased on visual content. Some implementations of technology describedherein generate an index of digital supplements that are relevant toparticular types of visual content and provide those digital supplementsin response to a visual-content query received from a client computingdevice. This index can allow a user to access relevant digitalsupplements that are provided by network-accessible resources (e.g., webpages) disposed throughout the world.

For example, a client computing device, such as a smartphone, maycapture an image of a supplement anchor, such as an entity. The clientcomputing device may then transmit a visual-content query based on theimage to a server computing device to retrieve digital supplementsassociated with the identified supplement anchor. In someimplementations, the supplement anchor is based on the physicalenvironment around the client computing device and the digitalsupplement is virtual content that may supplement a user's experience inthe physical environment.

The visual-content query may include the image or data that isdetermined from the image (e.g., such as an indicator of the identifiedsupplement anchor). An example of data determined from the image is textthat is extracted from the image using, for example, optical characterrecognition. Other examples of data extracted from the image includevalues read from barcodes, QR codes, etc., in the image, identifiers ordescriptions of entities, products, or entity types identified in theimage.

The entities, products, or entity types may be identified in the imageusing, for example, a neural network system such as a convolutionalneural network system. The identifiers or descriptions of entities,products, or entity types may include metadata or a reference to arecord in a database that relates to an entity, product, or entity type.Non-limiting examples of the entities include buildings, works of art,products, books, posters, photographs, catalogs, signs, documents (e.g.,business cards, receipts, coupons, catalogs), people, and body parts.

Various types of digital supplements may be available that are relatedto a supplement anchor. The digital supplement may be provided by anetwork-accessible resource, such as a web page that is available on theInternet. There is a need for a way to locate and provide these digitalsupplements in response to a visual-content query. Some implementationsgenerate and maintain an index of digital supplements that areassociated with entities for use in responding to visual contentqueries. The index may, for example, be populated by crawlingnetwork-accessible resources to determine whether the network-accessibleresources include or provide any are digital supplements and todetermine the supplement anchors associated with those digitalsupplements.

For example, the network-accessible resource may include metadata thatidentifies the supplement anchors (e.g., text, codes, entities, or typesof entities) for which a digital supplement is associated. The metadatamay be included by the network-accessible resource in response to ahypertext transfer protocol (HTTP) request. The metadata may be providedin various formats such as extensible markup language (XML), JavaScriptObject Notation (JSON), or another format.

The metadata for a digital supplement may include one or more of thefollowing: a type indicator, an anchor indicator, a name, a description,a snippet of the content (i.e., an excerpt or preview of a portion ofthe content), an associated image, a link such as a URL to the digitalsupplement, and an identifier of an application associated with thedigital supplement. The metadata may also include information about apublisher of the digital supplement. For example, the metadata mayinclude one or more of a publisher name, a publisher description, and animage or icon associated with the publisher. In some implementations,the metadata includes context information related to providing thedigital supplement. For example, the metadata may also includeconditions (e.g., geographic conditions, required applications)associated with providing or accessing the digital supplement.

The identified digital supplements may be added to an index that isstored in a memory. In at least some implementations, the associatedsupplement anchor for a digital supplement is used as a key to theindex. The digital supplements may also be associated with variousscores. For example, a digital supplement may be associated with aprestige score that is based on how many other links are found (e.g.,while crawling network-accessible resources) that reference the digitalsupplement or the network-accessible resource associated with thedigital supplement and the prestige of the network-accessible resourcesthat provide those links. As another example, a digital supplement maybe associated with one or more relevance scores that correspond to therelevance of the digital supplement (or the associatednetwork-accessible resource) to a particular anchor. The relevance scoremay also be associated with a keyword or subject matter. The relevancescore may be determined based on one or more of the content of thedigital supplement, the content of the network-accessible resource, thecontent of sites that link to the network-accessible resource, and thecontents (e.g., text) of links to the network-accessible resources.

FIG. 1 is a block diagram illustrating a system 100 according to anexample implementation. The system 100 may associate digital supplementwith entities or entity types and may retrieve digital supplements inresponse to visual searches. A visual search is a search based onvisual-content. For example, a visual search may be performed based on avisual-content query. A visual-content query is a query based on animage or other visual-content. For example, a visual-content query mayinclude an image. In some implementations, a visual-content query mayinclude text or data that is based on an image. For example, the text ordata may be generated by recognizing one or more entities in an image.Some visual-content queries do not include an image (e.g., avisual-content query may include only data or text generated from animage). In some implementations, the system 100 includes a clientcomputing device 102, a search server 152, and a digital supplementserver 172. Also shown is a network 190 over which the client computingdevice 102, the search server 152, and the digital supplement server 172may communicate.

The client computing device 102 may include a processor assembly 104, acommunication module 106, a sensor system 110, and a memory 120. Thesensor system 110 may include various sensors, such as a camera assembly112, an inertial motion unit (IMU) 114, and a global positioning system(GPS) receiver 116. Implementations of the sensor system 110 may alsoinclude other sensors, including, for example, a light sensor, an audiosensor, an image sensor, a distance and/or proximity sensor, a contactsensor such as a capacitive sensor, a timer, and/or other sensors and/ordifferent combinations of sensors. In some implementations, the clientcomputing device 102 is a mobile device (e.g., a smartphone).

The camera assembly 112 captures images or videos of the physical spacearound the client computing device 102. The camera assembly 112 mayinclude one or more cameras. The camera assembly 112 may also include aninfrared camera. Image captured with the camera assembly 112 may be usedto identify to supplement anchors and to form visual content queries.

In some implementations, images captured with the camera assembly 112may also be used to determine a location and orientation of the clientcomputing device 102 within a physical space, such as an interior space,based on a representation of that physical space that is received fromthe memory 120 or an external computing device. In some implementations,the representation of a physical space may include visual features ofthe physical space (e.g., features extracted from images of the physicalspace). The representation may also include location-determination dataassociated with those features that can be used by a visual positioningsystem to determine location and/or position within the physical spacebased on one or more images of the physical space. The representationmay also include a three-dimensional model of at least some structureswithin the physical space. In some implementations, the representationdoes not include three-dimensional models of the physical space.

The IMU 114 may detect motion, movement, and/or acceleration of theclient computing device. The IMU 114 may include various different typesof sensors such as, for example, an accelerometer, a gyroscope, amagnetometer, and other such sensors. An orientation of the clientcomputing device 102 may be detected and tracked based on data providedby the IMU 114 or GPS receiver 116.

The GPS receiver 116 may receive signals emitted by GPS satellites. Thesignals include a time and position of the satellite. Based on receivingsignals from several satellites (e.g., at least four), the GPS receiver116 may determine a global position of the client computing device 102.

The memory 120 may include an application 122, other applications 140,and a device positioning system 142. The other applications 140 includeany other applications that are installed or otherwise available forexecution on the client computing device 102. In some implementations,the application 122 may cause one of the other applications 140 to belaunched to provide a digital supplement. In some implementations, somedigital supplements may only be available if the other applications 140include a specific application associated with or required to providethe digital supplement.

The device positioning system 142 determines a position of the clientcomputing device 102. The device positioning system 142 may use thesensor system 110 to determine a location and orientation of the clientcomputing device 102 globally or within a physical space. In someimplementations, the device positioning system 142 determines a locationof the client computing device 102 based on, for example, a cellulartriangulation.

In some implementations, the client computing device 102 may include avisual positioning system that compares images captured by the cameraassembly 112 (or features extracted from those images) to a knownarrangement of features within the representation of the physical spaceto determine the six degree-of-freedom pose (e.g., the location andorientation) of the client computing device 102 within a physical space.

The application 122 may include a supplement anchor identificationengine 124, a digital supplement retrieval engine 126, a digitalsupplement presentation engine 128, and a user interface engine 130.Some implementations of the application 122 may include fewer,additional, or other components.

The supplement anchor identification engine 124 identifies supplementanchors based on, for example, images captured with the camera assembly112. In some implementations, the supplement anchor identificationengine 124 analyzes an image to identify text. The text may then be usedto identify an anchor. For example, the text may be mapped to a node ina knowledge graph. For example, the text may be recognized as the nameof an entity such as a person, place, product, building, artwork, movie,or other type of entity. In some implementations, the text may berecognized as a phrase that is commonly associated with a specificentity or as a phrase that describes a specific entity. For example, thetext may then be recognized as an anchor associated with the specificentity.

In some implementations, the supplement anchor identification engine 124identifies one or more codes, such as a barcode, QR code, or anothertype of code, within an image. The code may then be mapped to asupplement anchor.

The supplement anchor identification engine 124 may include a machinelearning module that can recognize at least some types of entitieswithin an image. For example, the machine learning module may include aneural network system. Neural networks are computational models used inmachine learning and made up of nodes organized in layers with weightedconnections. Training a neural network uses training examples, eachexample being an input and a desired output, to determine, over a seriesof iterative rounds, weight values for the connections between layersthat increase the likelihood of the neural network providing the desiredoutput for a given input. During each training round, the weights areadjusted to address incorrect output values. Once trained, the neuralnetwork can be used to predict an output based on provided input.

In some implementations, the neural network system includes aconvolution neural network (CNN). A convolutional neural network (CNN)is a neural network in which at least one of the layers of the neuralnetwork is a convolutional layer. A convolutional layer is a layer inwhich the values of a layer are calculated based on applying a kernelfunction to a subset of the values of a previous layer. Training theneural network may involve adjusting weights of the kernel functionbased on the training examples. Typically, the same kernel function isused to calculate each value in a convolutional layer. Accordingly,there are far fewer weights that must be learned while training aconvolutional layer than a fully-connected layer (e.g., a layer in whicheach value in a layer is a calculated as an independently adjustedweighted combination of each value in the previous layer) in a neuralnetwork. Because there are typically fewer weights in the convolutionallayer, training and using a convolutional layer may require less memory,processor cycles, and time than would an equivalent fully-connectedlayer.

After the supplement anchor identification engine 124 recognizes anentity or entity type in an image, a textual description of the entityor entity type may be generated. Additionally, the entity or entity typemay be mapped to a supplement anchor. In some implementations, asupplement anchor is associated with one or more digital supplements.

In some implementations, the supplement anchor identification engine 124determines a confidence score for a recognized anchor. A higherconfidence score may indicate that the content (e.g., image, extractedtext, barcode, QR code) from an image is more likely to be associatedwith the determined anchor than if a lower confidence score isdetermined.

Although the example of FIG. 1 shows the supplement anchoridentification engine 124 as a component of the application 122 on theclient computing device 102, some implementations include a supplementanchor identification engine on the search server 152. For example, theclient computing device 102 may send an image captured by the cameraassembly 112 to the search server 152, which may then identifysupplement anchors within the image.

In some implementations, the supplement anchor identification engine 124identifies potential supplement anchors. For example, the supplementanchor identification engine 124 may identify (recognized) variousentities within an image. Identifiers of the recognized entities maythen be transmitted to the search server 152, which may determine if anyof the entities are associated with any supplement anchors. In someimplementations, the search server 152 may use the identified entitiesas contextual information even if the identified entities are notsupplement anchors.

The digital supplement retrieval engine 126 retrieves digitalsupplements. For example, the digital supplement retrieval engine 126may retrieve digital supplements associated with supplement anchorsidentified by the supplement anchor identification engine 124. In someimplementations, the digital supplement retrieval engine 126 retrieves adigital supplement from the search server 152 or the digital supplementserver 172.

For example, after supplement anchors are identified, the digitalsupplement retrieval engine 126 may retrieve one or more digitalsupplements that are associated with the identified supplement anchors.The digital supplement retrieval engine 126 may generate avisual-content query that includes the image (or identifiers ofsupplement anchors or entities within the image) and transmit thevisual-content query to the search server 152. The visual-content querymay also include contextual information such as the location of theclient computing device 102. In some implementations, data relating tothe digital supplements such as a name, an image, or a description isretrieved and presented to a user (e.g., by the user interface engine130). If multiple digital supplements are presented, a user may selectone of the digital supplements via a user interface generated by theuser interface engine 130.

The digital supplement presentation engine 128 presents or causesdigital supplements to be presented on the client computing device 102.In some implementations, the digital supplement presentation engine 128causes the client computing device to initiate one of the otherapplications 140. In some implementation, the digital supplementpresentation engine 128 causes information or content to be displayed.For example, the digital supplement presentation engine 128 may causethe user interface engine 130 to generate a user interface that includesinformation or content from a digital supplement to be displayed by theclient computing device 102. In some implementations, the digitalsupplement presentation engine 128 is triggered by the digitalsupplement retrieval engine 126 retrieving a digital supplement. Thedigital supplement presentation engine 128 may then trigger the displaydevice 108 to display content associated with a digital supplement. Insome implementations, the digital supplement presentation engine 128causes a digital supplement to be displayed at a different time thanwhen the digital supplement retrieval engine 126 retrieves the digitalsupplement. For example, a digital supplement may be retrieved inresponse to a visual-content query at a first time and the digitalsupplement may be presented at a second time. For example, a digitalsupplement may be retrieved in response to a visual-content query basedon an image of a home furnishing or furniture from a catalog or store ata first time (e.g., while the user is looking through a catalog or is ata store). A digital supplement that includes AR content of the homefurnishing or furniture may be presented at a second time (e.g., whilethe user is in a room in which the home furnishing or furniture may beplaced).

The user interface engine 130 generates user interfaces. The userinterface engine 130 may also cause the client computing device 102 todisplay the generated user interfaces. The generated user interfacesmay, for example, display information or content from a digitalsupplement. In some implementations, the user interface engine 130generates a user interface includes multiple user-actuatable controlsthat are each associated with a digital supplement. For example, a usermay actuate one of the user-actuatable controls (e.g., by touching thecontrol on a touchscreen, clicking on the control using a mouse oranother input device, or otherwise actuating the control).

The search server 152 is a computing device. The search server 152 mayrespond to search requests such as visual-content queries. The responsemay include one or more digital supplements that are potentiallyrelevant to the visual-content query. In some implementations, thesearch server 152 includes memory 160, a processor assembly 154, and acommunication module 156. The memory 160 may include a content crawler162, a digital supplement search engine 164, and a digital supplementdata store 166.

The content crawler 162 may crawl network-accessible resources toidentify digital supplements. For example, the content crawler 162 mayaccess web pages that are accessible via the Internet, such as web pagesprovided by the digital supplement server 172. Crawling anetwork-accessible resource may include requesting the resource from aweb server and parsing at least a portion of the resource. Digitalsupplements may be identified based on metadata provided by thenetwork-accessible resource, such as XML or JSON data that providesinformation about a digital supplement. In some implementations, thecrawler identifies network-accessible resources based on extractinglinks from previously crawled network-accessible resources. The contentcrawler 162 may also identify network-accessible resources to crawlbased on receiving input submitted by a user. For example, a user maysubmit a URL (or other information) to a network-accessible resourcethat includes a digital supplement via a web form or applicationprogramming interface (API). In some implementations, the contentcrawler 162 generates an index of the identified digital supplement. Thecontent crawler 162 may also generate scores associated with the digitalsupplements, such as relevance scores or popularity (prestige) scores.

The digital supplement search engine 164 receives search queries andgenerates responses that may include one or more potentially relevantdigital supplement. For example, the digital supplement search engine164 may receive a visual-content query from the client computing device102. The visual-content query may include an image. The digitalsupplement search engine 164 may identify supplement anchors in theimage and, based on the identified supplement anchor, identify relatedor potentially relevant digital supplements. The digital supplementsearch engine 164 may transmit to the client computing device 102 aresponse that includes the digital supplement or information that can beused to access the digital supplement. In some implementations, thedigital supplement search engine 164 may return information associatedwith multiple digital supplements. For example, a list of digitalsupplements may be included in a response to the query. The list may beordered based on relevance to the supplement anchor, popularity, orother properties of the digital supplement.

The visual-content queries may, for example, include images captured bythe camera assembly 112 or text or other data associated with imagescaptured by the camera assembly 112. The visual-content queries may alsoinclude other information such as the location of the client computingdevice 102 or an identifier of a user of the client computing device102. In some implementations, the search server 152 may determine aprobably location of the client computing device 102 from the useridentifier (e.g., if the user has enabled a location service on theclient computing device 102 that associates information about a user'slocation with the user's account).

The digital supplement data store 166 stores information about digitalsupplements. In some implementations, the digital supplement data store166 includes an index of digital supplements. For example, the index maybe generated by the content crawler 162. The digital supplement searchengine 164 may use the index to respond to search queries.

The digital supplement server 172 is a computing device. The digitalsupplement server 172 provides digital supplements. In someimplementations, the digital supplement server 172 includes memory 180,a processor assembly 174, and a communication module 176. The memory 180may include a digital supplement 182 and metadata 184. In someimplementations, the memory 180 may also include othernetwork-accessible resources such as web pages that are not necessarilydigital supplements. For example, the memory 180 may store a web pagethat includes metadata to provide details about one or more digitalsupplements and how to access those digital supplements. Additionally,the memory 180 may include a resource serving engine such as a webserver that, for example, responds to requests, such as HTTP requests,with network-accessible resources such as web pages and digitalsupplements.

The digital supplement 182 is content of any type that can be providedas a supplement to something in the physical environment around a user.The digital supplement 182 may also include content of any type that cansupplement a stored image (e.g., of a previous physical environmentaround a user). For example, the digital supplement may be associatedwith a supplement anchor, such as an image, an object or productidentified in the image, or a location. The digital supplement 182 mayinclude one or more images, audio content, textual data, videos, games,data files, applications, or structured text documents. Examples ofstructured text documents include hypertext markup language (HTML)documents, XML documents, and other types of structured text documents.

The digital supplement 182 may cause an application to be launched andmay define parameters for that application. The digital supplement 182may also cause a request to be transmitted to a server (e.g., an HTTPrequest) and may define parameters for that request. In someimplementations, the digital supplement 182 initiates as a workflow forcompleting an activity, such as a workflow for completing a purchase.For example, the digital supplement 182 may transmit an HTTP request toa server that adds a particular product to a user's shopping cart, addsa coupon code, and retrieves a purchase confirmation page.

The metadata 184 is data that describes a digital supplement. Themetadata 184 may describe one or digital supplements that are providedby the digital supplement server 172 or that are provided elsewhere. Themetadata 184 for a digital supplement may include one or more of thefollowing: a type indicator, an anchor indicator, a name, a description,a preview snippet or excerpt, an associated image, a link such as a URLto the digital supplement, and an identifier of an applicationassociated with the digital supplement. The metadata may also includeinformation about a publisher of the digital supplement, such as apublisher name, a publisher description, and an image or icon associatedwith the publisher. In some implementations, the metadata also includescontext information about the digital supplement or that must besatisfied to provide the digital supplement. For example, the metadatamay include conditions (e.g., geographic conditions, client computingdevices requirements, required applications) that must be met to accessthe digital supplement. Example context information includes locations,entities identified within an image, or multiple entities identifiedwithin an image (e.g., some digital supplements may require acombination of entities to be recognized within the image). Therecognized entities may be supplement anchors. In some implementations,the recognized entities are not supplement anchors but instead providecontextual information. The metadata 184 may also include supplementanchors (e.g., text, codes, entities, or types of entities) that areassociated with a digital supplement.

The metadata 184 may be stored in various formats. In someimplementations, the metadata 184 is stored in database. The metadata184 may also be stored as an XML file, a JSON file or another formatfile. In some implementations, the digital supplement server 172retrieves the metadata 184 from a database and formats the metadata 184as XML, JSON, or otherwise to provide a response to a request from aclient or the search server 152. For example, the search server 152 mayaccess the metadata 184 to generate data stored in the digitalsupplement data store 166 and used to respond to search requests fromthe client computing device 102.

The communication module 106 includes one or more devices forcommunicating with other computing devices, such as the search server152 or the digital supplement server 172. The communication module 106may communicate via wireless or wired networks, such as the network 190.The communication module 156 of the search server 152 and thecommunication module 176 of the digital supplement server 172 may besimilar to the communication module 106.

The display device 108 may, for example, include an LCD (liquid crystaldisplay) screen, an LED (light emitting diode) screen, an OLED (organiclight emitting diode) screen, a touchscreen, or any other screen ordisplay for displaying images or information to a user. In someimplementations, the display device 108 includes a light projectorarranged to project light onto a portion of a user's eye.

The memory 120 can include one or more non-transitory computer-readablestorage media. The memory 120 may store instructions and data that areusable by the client computing device 102 to implement the technologiesdescribed herein, such as to generate visual-content queries based oncaptured images, transmit visual-content queries, receive responses tothe visual-content queries, and present a digital supplement identifiedin a response to a visual-content query. The memory 160 of the searchserver 152 and the memory 180 of the digital supplement server 172 maybe similar to the memory 120 and may store data instructions that areusable to implement the technology of the search server 152 and thedigital supplement server 172, respectively.

The processor assembly 104 includes one or more devices that are capableof executing instructions, such as instructions stored by the memory120, to perform various tasks associated with digital supplementassociation and retrieval for visual search. For example, the processorassembly 104 may include a central processing unit (CPU) and/or agraphics processor unit (GPU). For example, if a GPU is present, someimage/video rendering tasks, such as generating and displaying a userinterface or displaying portions of a digital supplement may beoffloaded from the CPU to the GPU. In some implementations, some imagerecognition tasks may also be offloaded from the CPU to the GPU.

Although FIG. 1 does not show it, some implementations include ahead-mounted display device (HMD). The HMD may be a separate device fromthe client computing device 102 or the client computing device 102 mayinclude the HMD. In some implementations, the client computing device102 communicates with the HMD via a cable. For example, the clientcomputing device 102 may transmit video signals and/or audio signals tothe HMD for display for the user, and the HMD may transmit motion,position, and/or orientation information to the client computing device102.

The client computing device 102 may also include various user inputcomponents (not shown) such as a controller that communicates with theclient computing device 102 using a wireless communications protocol. Insome implementations, the client computing device 102 may communicatevia a wired connection (e.g., a Universal Serial Bus (USB) cable) or viaa wireless communication protocol (e.g., any WiFi protocol, anyBlueTooth protocol, Zigbee, etc.) with a HMD (not shown). In someimplementations, the client computing device 102 is a component of theHMD and may be contained within a housing of the HMD.

The network 190 may be the Internet, a local area network (LAN), awireless local area network (WLAN), and/or any other network. The clientcomputing device 102, for example, may receive the audio/video signals,which may be provided as part of a digital supplement in an illustrativeexample implementation, via the network.

FIG. 2 is a third person view of an example physical space 200 in whichan embodiment of the client computing device 102 is accessing digitalsupplements. In this example, the physical space 200 includes an object222. Here, the object 222 is an artwork on a wall of the physical space200. The object 222 is contained within the field of view 204 of thecamera assembly 112 of the client computing device 102.

An example user interface screen 206 is also shown. The user interfacescreen 206 may, for example, be generated by the user interface engine130 of the client computing device 102. The user interface screen 206includes an image display panel 208, and a digital supplement selectionpanel 210. The image display panel 208 shows an image. For example, theimage display panel 208 may show an image corresponding to a real-timefeed from the camera assembly 112 of the client computing device 102. Insome implementations, the image display panel 208 shows a previouslycaptured image or an image that has been retrieved from the memory 120of the client computing device 102.

In some implementations, the user interface screen 206 is displayed tothe user on a display device of the client computing device 102. In someimplementations, the user interface screen 206 may be overlaid on animage (or video feed being captured by the camera of the computingdevice) of the physical space so. Additionally, the user interfacescreen 206 may be displayed as AR content over the user's field of viewusing an HMD worn by the user.

The image display panel 208 may also include annotations or userinterface elements that may relate to the image. For example, the imagedisplay panel 208 may include an indicator that an object in the image(e.g., the object 222) has been recognized as a supplement anchor. Theindicator may include a user-actuatable control to access or viewinformation about digital supplements associated with the identifiedsupplement anchor. In some situations, the image displayed in the imagedisplay panel 208 may include multiple objects that are recognized assupplement anchors, and the image display panel 208 may include multipleannotations that overlay the image to identify those supplement anchors.

The supplement anchors may be recognized by a supplement anchoridentification engine of the client computing device 102. In someimplementations, the supplement anchors are identified by transmittingan image to the search server 152. The search server 152 may thenanalyze the image and identify supplement anchors in the image. In someimplementations, the search server 152 may transmit one or more of thelocations (e.g., image coordinates) or the dimensions of any identifiedobjects that are associated with supplement anchors to the clientcomputing device 102. The client computing device 102 may then updatethe user interface screen to show annotations that identify thesupplement anchors (or associated objects) in the image. In someimplementations, the client computing device 102 may track the locationsof the supplement anchors (or associated objects) in a video stream(e.g., a sequence sequentially captured images) captured by the cameraassembly 112 (e.g., the supplement anchor identification engine 124 maytrack supplement anchors identified by the search server 152).

The digital supplement selection panel 210 allows a user to select adigital supplement for presentation. For example, the digital supplementselection panel 210 may include a menu that includes user-actuatablecontrols that are each associated with a digital supplement. In thisexample, the digital supplement selection panel 210 includes auser-actuatable control 212 and a user-actuatable control 214, whicheach include information about the associated digital supplement. Forexample, the user-actuatable controls may display one or more of a name(or title), a brief description, and an image associated with thedigital supplements, which may be received from the search server 152.Upon actuation of the user-actuatable control 212 or the user-actuatablecontrol 214, the content of the associated digital supplement may bepresented to the user. Presenting the digital supplement to the user mayinclude causing the client computing device 102 to display a userinterface screen that includes images, videos, text, other content, or acombination thereof from the digital supplement. In someimplementations, the digital supplement content is displayed as anoverlay on the image display panel 208 over an image or camera feed. Thedigital supplement content may be three-dimensional augmented realitycontent.

In some implementations, presenting a digital supplement includesactivating an application that is installed on the client computingdevice 102 (e.g., one of the other applications 140). Presenting thedigital supplement may also include transmitting a request to a URLassociated with the digital supplement. The request may includeparameters associated with the digital supplement, such as an identifierof a product or object identified within the image. In someimplementations, the image (or other content) from the visual-contentquery is passed a parameter with the request. The image may also beprovided via an API associated with a digital supplement server 172. Insome implementations, the client computing device 102 transmits theimage to the digital supplement server 172. In some implementations, thesearch server 152 may transmit the image to the digital supplementserver 172. For example, responsive to a user selecting a digitalsupplement, the client computing device 102 may transmit an indicator ofthe selection to the search server 152 and the search server 152 maythen transmit the image to a corresponding digital supplement server.The client computing device 102 may also transmit a URL to a location onthe search server 152 that the digital supplement server 172 can use toaccess the image. Beneficially, these implementations may reduce theamount of data the client computing device needs to transmit.

The digital supplement associated with the user-actuatable control 212may cause information about the object 222, such as information from amuseum, to be displayed. The digital supplement associated with theuser-actuatable control 214 may cause information related to a museumtour to be displayed. For example, presentation of the digitalsupplement may cause a stop on a museum tour to be marked as completedand information about a next stop to be displayed.

FIG. 3 is a diagram of an example method 300 of enabling triggering of adigital supplement, in accordance with implementations described herein.This method 300 may, for example, be performed by the content crawler162 of the search server 152 to allow a user to access a digitalsupplement based on a visual-content query.

At operation 302, data specifying a digital supplement is received. Thedata may identify a digital supplement and situations in which thedigital supplement should be provided. The data specifying a digitalsupplement may be received in various ways. For example, the dataspecifying the digital supplement may be received from anetwork-accessible resource such as a web page that includes metadataabout the digital supplement. The data specifying a digital supplementmay also be received via an API or form provided by, for example, thesearch server 152. The data specifying a digital supplement may also bereceived from a memory location or data store.

The data about the digital supplement may include access data that isusable by a client computing device to access the digital supplement.For example, the access data may include a URL of the digital supplementand parameters to pass to that URL. The access data may also include anapplication identifier and parameters for the application. The dataabout the digital supplement may also include descriptive data about thedigital supplement. The descriptive data may be usable by a clientcomputing device to present information about a digital supplement to auser (e.g., on a menu in which the user may select a digitalsupplement). The descriptive data may include, for example, a name (ortitle, a description, a publisher name, and an image. The data about thedigital supplement may also include identifiers of supplement anchors.

At operation 304, a data structure instance based on the received datais generated. The data structure may, for example, be a record in adatabase. The database may be a relational database and the datastructure instances may be linked (e.g., via a foreign key) with one ormore records associated with supplement anchors.

At operation 306, after generating the data structure instance,retrieval of the digital supplement by a visual-content query isenabled. For example, a database field associated with the datastructure instance may be set to active so that the digital supplementsearch engine 164 can access and return the associated digitalsupplement. In some implementations, triggering of the digitalsupplement may include saving or committing a database record. In someimplementations, enabling of retrieval of the digital supplementincludes enabling triggering of the digital supplement by a clientcomputing device. For example, after the instance is generated, thedigital supplement may be returned to a client computing device inresponse to a search and activated or presented by the client computingdevice.

FIG. 4 is a diagram of an example method 400 of enabling triggering of adigital supplement, in accordance with implementations described herein.This method 400 may, for example, be performed by the content crawler162 of the search server 152 to allow a user to access a digitalsupplement based on a visual-content query.

At operation 402, a network-accessible resource is analyzed. In someimplementations, the network accessible resource is a web page servedby, for example, the digital supplement server 172. In someimplementations, a set of network-accessible resources are analyzed. Theset of network-accessible resources may be generated based onsubmissions via a form or API. In some implementations, the set ofnetwork-accessible resources may be generated by crawling othernetwork-accessible resources to identify URLs. This crawling process maybe performed recursively.

At operation 404, metadata associated with a digital supplement withinthe network-accessible resource is identified. In some implementations,the network-accessible resource may include an indicator of metadataassociated with a digital supplement. For example, thenetwork-accessible resource may include a tag that identifies a portionof the network-accessible resource that includes the metadata. The tagmay be an XML tag with a specific type or attribute. The tag may be anHTML tag, such as a script tag that includes a JSON data structurecontaining metadata.

At operation 406, a digital supplement data structure instance based onthe metadata is generated. The operation 406 may be similar to theoperation 304.

At operation 408, a visual-content query is received. The visual-contentquery may for example be sent by a client computing device such as theclient computing device 102. In some implementations, the visual-contentquery includes an image. The visual-content query may also includetextual data that describes an image. For example, the textual data mayinclude identifiers of supplement anchors within an image captured by acamera assembly of the client computing device. In some implementations,the visual-content query also includes other information, such as alocation of the client computing device or an identifier of a useraccount associated with the client computing device.

At operation 410, multiple digital supplement data structures instancesare identified based on the visual-content query. In someimplementations, supplement anchors are identified within an imageprovided in the visual-content query. The supplement anchors may then beused to query an index or a database for relevant digital supplements.In some implementations, other data provided with the query may be usedto identify the digital supplements too, such as a location of theclient computing device or information associated with a user account.In some implementations, multiple supplement anchors are used toidentify relevant supplement anchors.

At operation 412, an ordering of the multiple digital supplement datastructure instances is determined. The ordering may be based on variousscores associated with the digital supplement or the relevance of thedigital supplement to the visual-content query. In some implementations,a relevance score that corresponds to the relevance of a digitalsupplement to the visual-content query is used to order the multipledigital supplement data structure instances.

The relevance score may be determined from multiple factors, such as oneor more of the content of the digital supplement, the content ofnetwork-accessible resources that link to the digital supplement (or anetwork-accessible resource associated with the digital supplement), thelink text or content near the links to the digital supplement on othernetwork-accessible resources.

The scores may also be based on popularity metrics. A prestige metric isan example of a popularity metric. The prestige metric may be based on acombination of how many other network resources link to the digitalsupplement and the prestige score of those other network-accessibleresources. In some implementations, the popularity score may be based onhow frequently the digital resource is or has been selected. In someimplementations, the popularity score may correspond to how frequentlythe digital resource is selected for the visual-content query.

The scores may be determined or may be retrieved from a data store or anAPI. In some implementations, an API is accessed to retrieve scores fora digital supplement. For example, the scores may be retrieved from asearch engine that has determined a relevance and/or popularity for adigital resource with respect to search terms that are based on thesupplement anchors.

The multiple digital supplement data structures may also be orderedbased on frequency of use by a specific user (e.g., the user of theclient computing device) or recency of use by the specific user. In someimplementations, the multiple digital supplement data structures areordered randomly.

At operation 414, the visual-content query is responded to based on themultiple digital supplement data structure instances. For example,information associated with the multiple digital supplement datastructure instances may be transmitted to the client computing device inthe order determined at operation 412. In some implementations, theinformation includes descriptive data that can be shown in a menu oranother type of user interface that is configured to receive a userselection of a digital supplement. The information may also includeaccess data that can be used by the client computing device to access orpresent the digital supplement.

FIG. 5 is a diagram of an example method 500 of searching for andpresenting a digital supplement, in accordance with implementationsdescribed herein. This method 500 may, for example, be performed by theapplication 122 of the client computing device 102 to identify andaccess a digital supplement based on a visual-content query.

At operation 502, a visual-content query that is based on an image istransmitted to a server computing device (e.g., the search server 152).For example, an image may be captured with the camera assembly 112 ofthe client computing device 102. The image may also be a stored imagesuch as an image that was previously captured by the camera assembly112. In some implementations, the visual-content query includes only theimage. In some implementations, the visual-content query includesadditional information. For example, the visual-content query mayinclude information such as a location of the client computing device102 or an identifier of an account associated with a user of the clientcomputing device 102. The application 122 may also identify anchors inan image (e.g., with the supplement anchor identification engine 124).The visual-content query may include identifiers (e.g., textual, numericor other types of identifiers) of the identified anchors. In at leastsome implementations, the visual-content query does not include animage.

In some implementations, transmitting the visual-content query to theserver includes calling an API. In some implementations, transmittingthe visual-content query to the server includes calling an API providedby the server. In some implementations, transmitting the visual-contentquery to the server includes submitting a form using the HTTP protocol(e.g., submitting a GET or POST request).

At operation 504, a response to the visual-content query that identifiesa digital supplement is received. The response may be received via thenetwork 190 from the search server 152. The response may include one ormore digital supplements that were identified based on thevisual-content query by the search server 152. For example, the responsemay include an array of data associated with the digital supplements. Insome implementations, the data associated with the digital supplementsmay include descriptive data that can be used to present digitalsupplement options for a user to select. For example, the descriptivedata may include a name, a short description, a publisher name, and animage. The data may also include access data, such as a URL andparameters to include with a request via the URL or an application nameand associated parameters. The data may also include the location,coordinates, or dimensions of supplement anchors in an image transmittedwith the visual-content query (e.g., if the supplement anchors areidentified by the search server 152).

At operation 506, a user interface screen that includes informationassociated with the digital supplement is displayed. In someimplementations, the user interface screen includes annotations thatoverlay the identified supplement anchors (e.g., based on the providedcoordinates). The annotations may provide information about the objectin the image associated with the identified supplement anchors. Theannotations may include user-actuatable controls that can be actuated topresent or activate a digital supplement. The user interface screen mayalso include a digital supplement selection panel that can be used toselect from multiple digital supplements that are identified in theresponse received at operation 504. In some implementations, the userinterface screen may be generated a by a web browser that opens a URLspecified by the digital supplement. The user interface screen may alsobe generated by another application that is launched to provide thedigital supplement.

FIG. 6 is a diagram of an example method 600 of identifying andpresenting a digital supplement based on an image, in accordance withimplementations described herein. This method 600 may, for example, beperformed by the application 122 of the client computing device 102 toidentify and access a digital supplement based on a visual-contentquery.

At operation 602, an image is captured. For example, the image may becaptured by the camera assembly 112 of the client computing device 102.In some implementations, a sequence of images (i.e., a video) may becaptured by the camera assembly 112.

At operation 604, a visual-content query that is based on the image istransmitted to a server computing device such as the search server 152.The operation 604 may be similar to the operation 502. Inimplementations, where a sequence of images are captured thevisual-content query may include multiple images or a sequence ofimages. In some implementations, the sequence of images may be streamedto the server computing device.

At operation 606, a response to the visual-content query that identifiesmultiple digital supplements is received. The operation 606 may besimilar to the previously described operation 504.

At operation 608, a user interface screen that includes user-actuatablecontrols to select a digital supplement from the multiple digitalsupplements is displayed. For example, a digital supplement selectionpanel may be displayed. The digital supplement selection panel mayinclude multiple user-actuatable controls each of which is associatedwith one of the multiple digital supplements identified in the response.The digital supplement selection may arrange the user-actuatablecontrols based on an ordering or ranking of the digital supplementsprovided by the server computing device. The digital supplementselection panel may arrange the user-actuatable controls vertically,horizontally, or otherwise. The user-actuatable controls may beassociated with or include information about the associated digitalsupplement that user can consider when deciding whether to select thedigital supplement. For example, the information that is displayed mayinclude one or more of a name, a description, an image, and a publishername for a digital supplement.

At operation 610, a user input to select a digital supplement isreceived. The user input may be a click using a mouse or other device.The user input may also be a touch input from a stylus or finger.Another example of a user input is a near-touch input (e.g., holding afinger or pointing device proximate to the screen). In someimplementations, the user input can also include a hand gesture, a headmotion, an action with an eye, or a spoken input.

At operation 612, information is provided to a resource associated withthe selected digital supplement. For example, information about a userof the client computing device may be transmitted to a server thatprovides the digital supplement (if permission to provide theinformation has been provided). The information may also be provided toan application that provides the digital supplement. Various types ofinformation may be provided. For example, the information may includeuser information such as a user name, user preferences, or a location.

The information may also include information related to thevisual-content query such as an image or sequence of images. Theinformation may also include identifiers and/or positions of one or moresupplement anchors in the image. This information may be used to providethe digital supplement to the user. For example, AR content of a digitalsupplement may be sized and positioned based on the image.

The information may be transmitted directly to the resource associatedwith the digital supplement (e.g., the digital supplement server 172) bythe client computing device 102. In some implementations, theinformation is provided to the resource associated with the digitalsupplement by the search server 152 (e.g., so the client computingdevice does not need to transmit as much data). In at least some ofthese implementations, the client computing device 102 may transmitselection information to the search server 152 that identifies aselected digital supplement. Upon receiving the selection and verifyingthat the user has authorized the sharing of the information, the searchserver 152 may then transmit information to the resource that providesthe digital supplement. The client computing device 102 may also promptthe user to permit sharing the information. In some implementations, thesearch server 152 may determine the information to transmit to theresource based on a digital supplement data structure instance (whichmay be based on metadata associated with the digital supplement).

At operation 614, the user interface is updated based on the selecteddigital supplement. The operation 614 may be similar to the operation506.

FIGS. 7A-7C are schematic diagrams of user interface screens displayedby embodiments of the client computing device 102 to conduct avisual-content search and display a digital supplement. In FIG. 7A auser interface screen 700 a is shown. The user interface screen 700 aincludes an image display panel 708 and an information panel 730. Inthis example, the image display panel 708 is displaying an image of ashelf full of wine bottles (e.g., as you might find in a store). Theimage display panel 708 also includes an indicator 740 and an indicator742. Each of these indicators indicate that the wine bottle shown in theimage beneath the indicator has been recognized as a supplement anchor(e.g., in this case as a recognized product). The indicator 740 and theindicator 742 are examples of user-actuatable controls. Within theinformation panel 730 instructions are provided to “Tap on what you'reinterested in.”

In FIG. 7B, a user interface screen 700 b is shown after a user hasactuated the indicator 740. After actuation, an annotation 744 from adigital supplement is displayed. The annotation 744 includes informationon the rating of the wine, which may help the user select a bottle ofwine to purchase.

In FIG. 7C, another user interface screen 700 c is shown after a userhas actuated the indicator 740. The user interface screen 700 c may beshown instead of or in addition to the user interface screen 700 b isshown (e.g., after actuation of the annotation 744 or if the user swipesup on the information panel 730 in FIG. 7B). In FIG. 7C, an expandedinformation panel 732 is shown. The expanded information panel 732 takesup more of the user interface screen 700 c than the information panel730 took up in FIGS. 7A and 7B.

The expanded information panel 732 includes a digital supplementselection panel 710 and a digital supplement content display panel 734.The digital supplement selection panel 710 includes a user-actuatablecontrol 712, a user-actuatable control 714, and a user-actuatablecontrol 716 (which is only partially visible). In some implementations,when a user swipes on the digital supplement selection panel 710additional user-actuatable controls may be displayed. Theuser-actuatable controls of the digital supplement selection panel 710may be arranged in a ranked order. The user-actuatable control 712 isassociated with a digital supplement for meal pairing. Upon actuation ofthe user-actuatable control 712, a digital supplement that displays foodand meal pairing information for the selected wine may be displayed. Theuser-actuatable control 714 is associated with a digital supplement thatsaves a photo. Upon actuation, an application that saves photos may beactivated and provided with the image. Additional information may besaved along with the photo such as the identified supplement anchors.

The digital supplement content display panel 734 may display contentfrom a digital supplement. The digital supplement content display panel734 may display a default digital supplement or a highest-ranked digitalsupplement that is associated with the identified supplement anchor. Inthis example, the digital supplement content display panel 734 includesproduct information about the product associated with the selectedsupplement anchor. In this case, a wine name, rating, location oforigin, image, and comments are provided.

FIGS. 8A-8C are schematic diagrams of user interface screens displayedby embodiments of the client computing device 102 to conduct avisual-content search and display a digital supplement. In this example,the visual-content search is based on an image of a receipt.

In FIG. 8A a user interface screen 800 a is shown. The user interfacescreen 800 a includes an image display panel 808 and an informationpanel 830. In this example, the image display panel 808 is displaying animage of a receipt from a restaurant. The image display panel 808 alsoincludes an indicator 840, an indicator 842, an annotation 844, and ahighlight overlay 846. In this case, the indicator 840 is associatedwith the receipt as a document, and the indicator 842 is associated witha specific restaurant named on the receipt. The identified receiptdocument and the identified restaurant name are both examples ofsupplement anchors.

The annotation 844 is associated with a digital supplement that providesa tip calculator. In this example, an example tip calculation isincluded on the annotation 844 and is overlaid at the appropriateposition on the image display panel 808. In some implementations, adigital supplement may be selected by default and displayed uponidentifying an appropriate supplement anchor. The highlight overlay 846is overlaid over a portion of the receipt document that includesinformation used by the tip calculator digital supplement.

In this example, the items displayed in the information panel 830 relateto the receipt as a document, as though the indicator 840 had beenactuated. In some implementations, identified supplement anchors areranked based on the likely relevance or interests of the user based, forexample, on the user's past actions, other user's actions for similarimages, confidence scores for the supplement anchors, or the position orsize of the portion of the image that the supplement anchors relate. Theinformation panel 830 may then display items related to the highestranked supplement anchor in at least some implementations. If instead,the indicator 842 were actuated the information panel 830 might includeitems about the specific restaurant.

Here, the information panel 830 includes a digital supplement selectionpanel 810. The digital supplement panel includes a user-actuatablecontrol 812, a user-actuatable control 814, and a user-actuatablecontrol 816. In this example, the user-actuatable control 812 isassociated with a tip calculator digital supplement, the user-actuatablecontrol 814 is associated with a check splitting digital supplement, andthe user-actuatable control 816 is associated with an expense reportdigital supplement. For example, upon actuation of the user-actuatablecontrol 812, user interface controls for adjusting parameters of the tipcalculator may be displayed (e.g., to adjust the percentage).

In FIG. 8B, a user interface screen 800 b is shown after a user hasactuated the user-actuatable control 814. After actuation, an expandedinformation panel 832 is shown that includes items to help a usercalculate how to split a check. For example, the number of peoplesplitting the check can be entered to determine the amount each shouldpay.

In FIG. 8C, a user interface screen 800 c is shown after a user hasactuated the user-actuatable control 816. After actuation, an expandedinformation panel 834 is shown that includes items to help a user storethe receipt to an expense report. For example, the user can select anexpense report with which the receipt should be associated (e.g.,“Sydney trip 2018”). Once the expense report is selected, an image ofthe receipt may be uploaded to an expense report submission ormanagement system. In some implementations, the full image that is shownon the image display panel 808 is uploaded. In some implementations, aportion of the image is uploaded (e.g., the image is cropped to includeonly the receipt).

FIGS. 9A and 9B are schematic diagrams of user interface screensdisplayed by embodiments of the client computing device 102 to conduct avisual-content search and display a digital supplement. In this example,the visual-content search is based on an image of a face.

In FIG. 9A a user interface screen 900 a is shown. The user interfacescreen 900 a includes an image display panel 908 and an informationpanel 930. In this example, the image display panel 908 is displaying animage of a face. Here, the face is an example of a supplement anchor.The information panel 930 includes a user-actuatable control 912 for adigital supplement that was identified for the supplement anchor in theimage (i.e., the face). The user-actuatable control 912 is associatedwith a digital supplement for tying on glasses.

In FIG. 9B, a user interface screen 900 b is shown after a user hasactuated the user-actuatable control 912. After actuation, an expandedinformation panel 932 is shown that includes items to help a uservisually try glasses on the face in the image. Here, multiple glassesstyles are displayed and the user can select a pair to try on. Uponselecting a pair of glasses, AR content 960 is overlaid on the imagedisplay panel 908. Here, the AR content 960 corresponds to the selectedglasses and is sized to match the face in the image. In someimplementations, when the digital supplement for trying on glasses isselected, the image shown in the image display panel 908 is transmittedto a server that provides the digital supplement so that the image canbe analyzed to determine where and how to position and size the ARcontent 960 or to recommend glasses to try on.

FIGS. 10A-10C are schematic diagrams of user interface screens displayedby embodiments of the client computing device 102 to conduct avisual-content search and display a digital supplement. In this example,the visual-content search is based on an image of furniture in acatalog.

In FIG. 10A, a user interface screen 1000 a is shown. The user interfacescreen 1000 a includes an image display panel 1008. In this example, theimage display panel 1008 is displaying an image of a portion of a pageof a furniture catalog. The image display panel also includes anindicator 1040, an indicator 1042, and an indicator 1044. In thisexample, the indicator 1040 is associated with a bed, the indicator 1042is associated with a decorative item, and the indicator 1044 isassociated with a rug. The images of the bed, the decorative item, andthe run in the catalog are examples of supplement anchors.

In FIG. 10B, a user interface screen 1000 b is shown after a user hasselected the indicator 1040 (e.g., by touching the screen at or nearwhere the indicator 1040 is displayed). The user interface screen 1000 bincludes a digital supplement selection panel 1010 and an informationpanel 1030. The information panel 1030 includes information (e.g., aproduct name, description, and image) about the supplement anchorassociated with the selected indicator.

The digital supplement selection panel 1010 includes a user-actuatablecontrol 1012 and a user-actuatable control 1014. The user-actuatablecontrol 1012 is associated with a digital supplement that provides anin-home view. The user-actuatable control 1014 is associated withanother digital supplement (e.g., a digital supplement for posting to asocial media site).

In FIG. 10C, a user interface screen 1000 c is shown after actuation ofthe user-actuatable control 1012. The user interface screen 1000 cincludes the image display panel 1008, a digital supplement selectionpanel 1010 and a reduced information panel 1032. The reduced informationpanel 1032 may include a user-actuatable control that when actuated maycause the information panel to pop-up and be displayed.

Here, the image display panel 1008 now displays an image of a room andincludes AR content 1060. The AR content 1060 includes a 3D model of thebed associated with the indicator 1040 overlaid on the image panel.

In the example of thelaser pointer in an AR space, the computing device 1350 appears as avirtual laser pointer in the computer-generated, 3D environment. As theuser manipulates the computing device 1350, the user in the AR spacesees movement of the laser pointer. The user receives feedback frominteractions with the computing device 1350 in the AR environment on thecomputing device 1350 or on the AR headset 1390. The user's interactionswith the computing device may be translated to interactions with a userinterface generated in the AR environment for a controllable device.
